Cooling structure of an air cushion

ABSTRACT

A cooling structure of an air cushion contains a body, and the body includes a plurality of air units, and each air unit includes a recess disposed on a top surface thereof, such that when a contacting portion of a user abuts against the body, the plurality of air units contact with the contacting portion, and the recesses form an airing space to cool a heat.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a cooling structure of an air cushion, and more particularly to an integral formed air cushion with a plurality of recesses.

2. Description of the Prior Art

A conventional air cushion is used on a waist support and a cushion of a chair, a cushion of a bicycle or motor, and a protective pad of a helmet. However, such an air cushion has poor cooling effect that can not expel heat effectively.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a cooling structure of an air cushion containing a body, and the body including a plurality of air units, and each air unit including a recess disposed on a top surface thereof, such that when a contacting portion of a user abuts against the body, the plurality of air units contact with the contacting portion, and the recesses form an airing space to cool a heat.

Another object of the present invention is to provide a cooling structure of an air cushion in which the plurality of air units are connected together to achieve an arc structure so that a temperature generates as the user's waist contacts with the number of air units, it is capable of being cooled by using the plurality of recesses, thus obtaining comfort.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.

Referring to FIG. 1, a cooling structure of an air cushion in accordance with a first embodiment of the present invention comprises a body 10, and the body 10 includes a plurality of air units 11, and each air unit 11 includes a recess 12 disposed on a top surface thereof; the body 10 also includes a number of first connectors 13, each first connector 13 is used to connect the plurality of air units 11 together as shown in FIG. 2 and includes a cross air tube 14 extending from the connector 13, the body 10 includes a plurality of second connectors 20, each connector 20 is provided to connect at least two air tubes 14 together, such that an air cushion is assembled.

Referring to FIG. 3, when a contacting portion 30 of a user abuts against the body 10, the plurality of air units 11 contact with the contacting portion 30, and the recesses 12 form an airing space to cool a heat.

With reference to FIG. 4, a cooling structure of an air cushion in accordance with a second embodiment of the present invention comprises a body 10 including a number of air units 11, and each air unit 11 includes a recess 12 disposed on a central portion of a top surface thereof; this air cushion is fixed on a cycling pants of a bicycle to absorb an impact force, hence the air units 11 are capable of being arranged on various types of air cushions.

As illustrated in FIGS. 5-7, a cooling structure of an air cushion in accordance with a third embodiment of the present invention comprises a number of air units 40 and a plurality of recesses 41 fixed on a top surface of the body, and the plurality of recesses 41 communicate with each other; the air cushion is severed on a chair 50 to support user's waist so that when the air cushion is fixed on a chair back 51, the user's waist contacts with the body of the air cushion to obtain pressure balance and support effect, and the air units 40 are connected together to achieve an arc structure so that a temperature generates as the user's waist contacts with the number of air units 40, it is capable of being cooled by using the plurality of recesses 41, thus obtaining comfort.

While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention. 

1. A cooling structure of an air cushion comprising a body, and the body including a plurality of air units, and each air unit including a recess disposed on a top surface thereof, such that when a contacting portion of a user abuts against the body, the plurality of air units contact with the contacting portion, and the recesses form an airing space to cool a heat.
 2. The cooling structure of the air cushion as claimed in claim 1, wherein a top surface of the recess is lower than that of the air unit.
 3. The cooling structure of the air cushion as claimed in claim 1, wherein the air units are connected together to achieve an arc structure and are capable of being arranged on various types of air cushions.
 4. The cooling structure of the air cushion comprises a number of air units and a plurality of recesses fixed on a top surface of the body, and the plurality of recesses communicate with each other; such that when a contacting portion of a user abuts against the body, the number of air units contact with the contacting portion, and the recesses form an airing space to cool a heat.
